Near-IR Spectroscopy and Population Synthesis of Super Star Clusters in NGC 1569

Andrea M. Gilbert, James R. Graham

We present H- and K-band NIRSPEC spectroscopy of super star clusters (SSCs) in the irregular starburst galaxy NGC 1569, obtained at the Keck Observatory. We fit these photospheric…

Three high-redshift millimeter sources and their radio and near-infrared identifications

F. Bertoldi, C. L. Carilli, K. M. Menten +11

We present millimeter wavelength detections of three faint sources that are most likely high-redshift starburst galaxies. For one of the sources, which was previously discovered wi…

The Nature of the Halo Population of NGC 5128 Resolved with NICMOS on the Hubble Space Telescope

Francine R. Marleau, James R. Graham, Michael C. Liu +1

We present the first infrared color-magnitude diagram (CMD) for the halo of a giant elliptical galaxy. The CMD for the stars in the halo of NGC 5128 (Centaurus A) was constructed f…

Measurement of [OIII] Emission in Lyman Break Galaxies

H. I. Teplitz, M. A. Malkan, C. C. Steidel +8

Measurements of [OIII] emission in Lyman Break galaxies (LBGs) at z>3 are presented. Four galaxies were observed with narrow-band filters using the Near-IR Camera on the Keck I 10-…

An excess of submm sources near 4C41.17: a candidate proto-cluster at z=3.8?

Rob J. Ivison, James S. Dunlop, Ian Smail +3

Biased galaxy-formation theories predict that massive galaxies at high redshifts should act as signposts to high-density environments in the early Universe, which subsequently evol…

Theoretical Predictions for Surface Brightness Fluctuations and Implications for Stellar Populations of Elliptical Galaxies

Michael C. Liu, Stephane Charlot, James R. Graham

(Abridged) We present new theoretical predictions for surface brightness fluctuations (SBFs) using models optimized for this purpose. Our predictions agree well with SBF data for g…
